The high-end water-pipe maker has sued dozens of head shops across New York City over knockoff bongs — making it clear that the underworld of knockoffs isn’t just limited to ladies handbags in Chinatown.

Through its US affiliate Sream Inc., Roor has accused a slew of well-known NYC retailers of hurting its reputation and enriching themselves by selling cheap knockoffs of its coveted glass bongs.

The Manhattan federal lawsuits target smoke shops, groceries and news stands across the city, including I-Vape on St. Mark’s Place.

In its lawsuit against I-Vape, Roor accused the retailer of misleading customers “to pay premium prices for low grade products that free rides on the Roor brand.”

“Defendant uses images and names confusingly similar to the Roor mark,” the lawsuit said.

The glass maker has even sent private investigators to go to shops and buy the fakes, according to the lawsuits.
